To determine recent changes in cigarette purchasing behaviour of 14- and 15-year-old students in New Zealand.
Nationwide cross-sectional surveys of fourth form students in 85 schools in New Zealand by means of an anonymous self-administered questionnaire collected in November 1992 and in November 1997.
Analyses were restricted to 4198 out of 11 824 total students in 1992, and 4526 out of a total of 11 350 in 1997, who were current smokers aged 14 and 15 years. Self-purchasing of cigarettes decreased by 37% (95% CI: -40, -34) from 1992 to 1997, adjusting for age, sex and ethnicity, while acquiring cigarettes from other people increased. There was decreased purchasing from dairies (-6%; 95% CI: -8, -4) and supermarkets (-9%; 95% CI: -16, -1) but increases from other sources such as take-away shops, tobacconists and vending machines. From 1992 to 1997, weekly buying increased by 23% (95% CI 16, 32), students who were refused a sale increased by 153% (95% CI 139, 169) and students who had difficulty in buying increased by 324% (95% CI 276, 379). The latter were less likely to buy weekly than students who did not have difficulty (31.1% vs 41.4%). Students who smoked < or =5 cigarettes per week were 32% (95% CI 13, 53) more likely to have difficulty in buying than students smoking >20 per week.
These results indicate major changes in cigarette purchasing behaviour between 1992 and 1997, when there was increased enforcement against underage sales of tobacco.
确定新西兰14岁和15岁学生近期的香烟购买行为变化。
1992年11月和1997年11月,通过匿名自填问卷的方式,对新西兰85所学校的四年级学生进行全国性横断面调查。
分析仅限于1992年11824名学生中的4198名,以及1997年11350名学生中的4526名,这些学生为14岁和15岁的现吸烟者。在对年龄、性别和种族进行调整后,1992年至1997年期间,自行购买香烟的行为减少了37%(95%置信区间:-40,-34),而从他人处获取香烟的行为增加了。从乳品店购买香烟的行为减少了(-6%;95%置信区间:-8,-4),从超市购买的行为减少了(-9%;95%置信区间:-16,-1),但从外卖店、烟草专卖店和自动售货机等其他来源购买的行为增加了。1992年至1997年期间,每周购买量增加了23%(95%置信区间16,32),被拒绝销售的学生增加了153%(95%置信区间139,169),购买困难的学生增加了324%(95%置信区间276,379)。与没有购买困难的学生相比,购买困难的学生每周购买香烟的可能性较小(31.1%对41.4%)。每周吸烟≤5支的学生比每周吸烟>20支的学生购买困难的可能性高32%(95%置信区间13,53)。
这些结果表明,1992年至1997年期间,在加强对向未成年人销售烟草的执法力度时,香烟购买行为发生了重大变化。
